I just got this NS-SP1600 speaker system dialed in and adjusted in back of a Yamaha RX-V995 AV reciever. I was totally blown away by the crisp clean and powerful sound that comes from this speaker system. The surround speakers are very small and mount easily to the wall or brackets with the threaded inserts in the back of the speakers. The sub fit easily under an end table and provides way more bass than most people would ever need. Im powering these speakers with way more than they need and they still sound awesome. Ive dialed my reciever up to about 12 to see when or if the speakers would distort, thats about 80 watts per speaker at 6 ohms. No distortion at all. Very impressive. Almost knocked all the stuff off of my shelves with that much volume and bass. I would recommend these speakers to anyone looking for a very high quality, low priced 5.1 system with a powered subwoofer. Great Buy.
